I fixed signals and the shell works great. So I went on a porting spree. I ported a further 15 core utilities from sbase, which includes ed(1), so now there is a text editor for Bunnix.
The real news, however, is that I somehow managed to port binutils, and you can assemble and link assembly programs on Bunnix now. I also got gcc to compile for Bunnix, but it has some bizzare issues I don't care to debug right now -- I didn't expect to get even that far.
